Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire monitoring and control panel that sounds a fire by sounding a district sound device when a fire is judged, and more particularly to an additional fire control panel after the district sound is stopped by operating the district sound stop switch. The present invention relates to a fire monitoring control panel that can appropriately control stop release for a fire.

[0002]

2. Description of the Related Art Conventionally, when a fire is detected by a fire detector connected to a detector line drawn from a fire monitoring and control panel, when a fire signal from the detector line is received and it is determined that a fire occurs, the main acoustic device In addition to ringing, the control is performed to ring the area sound device such as the area bell installed in the warning area.

Further, a district sound stop switch is provided on the fire monitoring and control panel, and at the time of a fire, the district sound stop switch is operated to stop the sounding of the district sound device, and a staff member visits the site to confirm the fire. After that, a release operation is performed to control the district audio device to ring again.

[0004]

However, in the control of such a conventional district sound device, once the district sound stop switch is stopped, the district sound device is operated unless the release operation is performed. Even if a fire is received from another detector line while controlling the stop state and checking the site by stopping the district sound at the first fire reception,
I couldn't ring the district audio system.

In addition, if it takes time to check the site, or if an unexpected situation occurs and the user cannot return, the district sound remains stopped despite the actual fire. The present invention, when the ringing is stopped by operating the district sound stop switch, by canceling the ringing stop by monitoring the time from the additional fire reception or the ringing stop, the ringing and stopping of the appropriate district sound device can be performed. It is an object to provide a fire monitoring control panel that is controlled.

[0006]

In order to achieve this object, the present invention is configured as follows. First, the present invention, when receiving a fire detection signal from a fire detector connected to a sensor line drawn out to a surveillance area and judging that it is a fire, an area acoustic device connected to a control line drawn out to the surveillance area. Targets the fire monitoring and control panel that sounds.

In the present invention for such a fire monitoring and control panel, the district sound stop switch for stopping the sounding of the district sound device and the operation of the district sound stop switch during the sounding of the district sound device are detected. In this case, when the sound of the district audio device is stopped, and when an additional fire detection signal from another detector line or another fire detector is received in this stopped state, the sound of the district audio device is again activated. It is characterized in that a district sound control unit for controlling the state (sequential ringing stop mode) is provided.

For this reason, when a fire is received, the district sound stop switch is operated to stop the sounding of the district sound device, and even if the site confirmation is carried out, the fire is received from another detector line or another fire detector. In this case, the district audio device is sounded again, and it is possible to notify without delay that a new fire has started or a fire has spread. Further, the district sound control unit controls to ring the district sound device again when the operation of the district sound stop switch is detected and the operation of the district sound stop switch is detected in this stopped state.

Further, the district sound control unit controls the district sound device to automatically ring again when a predetermined time has elapsed after the sound of the district sound device was stopped by operating the district sound stop switch. For this reason, even if it takes time to check the site or if it is not possible to return due to an unexpected situation, the district audio system automatically sounds after a certain period of time, for example, 3 minutes, has passed since the district acoustics stopped, and there was a real fire. Nevertheless, it is possible to avoid the situation where the sound of the district audio device remains stopped.

Further, when it is detected that the operation of the district sound stop switch has continued for a predetermined time, for example, 3 seconds or longer, the district sound control unit sends a signal from another detector line or another fire detector in this stopped state. It is characterized by controlling to a forced stop state (forced stop mode) in which the ringing stop of the district audio device is maintained even when the additional fire detection signal is received. In other words, if the operation of the district sound stop switch is continued for 3 seconds,
This operation time is discriminated and the forced stop state is set. Even if an additional fire signal is received, the district sound is not re-ringed.
After entering the forced stop state, the control of the forced stop state can be released when it is detected that the operation of the district sound stop switch has continued for a predetermined time, for example, 1 second or longer.

This forced stop state can be set by continuing operation of the district sound stop switch in the steady monitoring state, or by continuing operation of the district sound stop switch when stopping the district sound device that has sounded due to fire reception. . The release of the forced stop state is the same. Furthermore, the district sound control unit controls the district sound stop light to blink in the sound stop state one after another, and controls the district sound stop light to turn on in the forced stop state so that the current setting state can be easily confirmed.

FIG. 3 shows the MPU 7 of the fire monitoring control board 1 of FIG.
First of the district sound control by the district sound control unit 14 provided in
It is a flow chart which showed control processing of an example. In the first embodiment of the district sound control unit 14 of FIG. 3, when the district sound device is sounded at the time of a fire determination, the district sound stop switch 17 is turned on to automatically stop the district sound. It is characterized in that the continuous ringing stop mode is set.

The continuous ringing stop mode means that the district audio device is automatically reactivated when an additional fire detection signal is received from another detector line or another fire detector while the district audio device is stopped. It is a mode to ring. That is, in the conventional district sound stop switch, when the switch operation is performed and the ringing of the district sound device is stopped, a fire detection signal is received from another detector line or another fire detector. However, the district sound device is not re-ringed, and the operation to release the stop of the district sound stop switch must be performed artificially.

However, in the sequential sound stop mode set in the first embodiment of FIG. 3, it is not necessary to release the stop of the district sound stop switch, and other sensor lines and Automatically re-ring the district audio system upon receipt of an additional fire detection signal from the fire detector. Further FIG.
In the first embodiment, the timer 15 is started in a state where the sequential sounding stop mode is set by stopping the district audio device, and the sequential sounding is automatically performed when a predetermined fixed time, for example, 3 minutes has elapsed. The feature is that the stop mode is canceled and the district audio device is re-ringed.

The control processing of the district sound control section 14 in the first embodiment of FIG. 3 will be described in detail as follows. Now, a fire detector 3 provided in the detector line 2-1 in FIG. 1 detects a fire, and the MPU 7 performs a storage operation or the like in response to a fire reception signal from the reception circuit 8-1 to perform a step S1.
Suppose it is a fire. Based on this fire determination, the district sound control unit 14 outputs a drive control signal to the district sound drive unit 12 in step S2 to ring the district bell 6 connected to the bell control line 5.

Of course, in the MPU 7, the main sound device 11 is sounded at the same time when the fire is judged, the fire representative lamp 19 provided on the display unit 10 is turned on, and the sensor line 2 through which the fire is received is sent. District indicator light 20-1 corresponding to 1
Lights up. In response to the alarm operation associated with the fire reception in the fire monitoring and control panel 1 as described above, the monitoring person is notified by the district indicator lamp 20.
From the display of -1, it is known that a fire has occurred in the area of the sensor line 2-1 and the area sound stop switch 17 is operated to temporarily stop the area bell 6 and go to the site confirmation.

Therefore, in step S2 of FIG.
Ring the district bell 6 as the district sound device, and then step S
After checking the ON of the recovery switch 18 in 3, the ON of the district sound stop switch 17 is checked in step S4, and if the ON operation is performed, in step S5, the district sound ringing for stopping the ringing of the district bell 6 is performed. Stop. When the stop of the ringing of the district sound is completed, the district sound control unit 14 sequentially sets the ringing stop mode in step S6. Then, in step S7, the timer 15 is started. Timer 15
In the state in which the step S8 has been started and the continuous ringing stop mode has been set, it is checked in step S8 whether or not the time of the timer 15 has been reached, that is, whether a preset set time, for example, 3 minutes has been reached, If not, it is checked in step S9 whether an additional fire has been received.

The additional fire means reception of fire from any of the sensor lines 2-2 to 2-n other than the sensor line 2-1 in which the fire is currently detected. In addition, in a system in which a unique address is set in the fire detector and this address can be identified by the fire monitoring and control panel, the additional fire includes the fire reception by the notification of another fire detector. If there is no additional fire, the ON operation of the district sound stop switch 17 is checked in step S10, and the ON operation of the recovery switch 18 is checked in step S11, and steps S8 to S1 are performed.
The process 1 is repeated. In this state, for example, if an additional fire due to a fire received from another sensor line is determined in step S9, the process proceeds to step 12, the currently set sequential ringing stop mode is released, and in step S13, the current operation is performed. The inner timer 15 is cleared, and the process proceeds to step S2 to re-ring the district audio device.

On the other hand, if the timer 15 reaches the set time of 3 minutes during the processing of steps S8 to S11 and the time is up,
Similarly, the ringing stop mode is canceled in step S12, the timer is cleared in step S13, and the process proceeds to step S2, in which the district audio device is automatically re-ringed. Further, when the ON operation of the district sound stop switch 17 is discriminated again in step S10 in the setting state of the sequential ringing stop mode in steps S8 to S11, similarly, step S1 is performed.
After releasing the mode in step 2, the timer 1 is set in step S13.
5 is cleared, and the district sound device is re-ringed in step S2.

When the recovery switch 18 is turned on in the monitoring state by the setting of the continuous ringing stop mode in steps S8 to S11, the timer 15 is cleared in step S14, and then a series of processing for recovering the fire reception state is performed. , Return to normal state. Of course, when the ON operation of the recovery switch 18 is determined in step S3 after the sounding of the district sound in step S2, the processing is similarly ended.

In the first embodiment of the district sound control section 14 according to the present invention shown in FIG. 3, the district sound stop switch 1 when the district sound device is activated when a fire is judged.
When the ringing is stopped by the operation of 7 and the ringing stop mode is set at the same time, and when the ringing stop mode is set, it is automatically detected when an additional fire due to a fire reception from another sensor line is determined. The mode is released and the district audio system is re-activated.

For this reason, even when the sound of the district sound device is stopped and the fire scene is being confirmed, if a fire occurs at the location of the other sensor line, regardless of whether the sound of the district sound is stopped or not. Re-ringing is automatically performed, and even in a situation in which a surveillance staff member is away from the fire monitoring and control panel 1, it is possible to reliably issue a fire alarm by the district audio device. In addition, even if the surveillance staff who went to the site confirmation could not return to the installation location of the fire monitoring control panel 1 due to a troublesome confirmation work or an unexpected situation, the timer started when the sequential ringing stop mode was set When the time is up, for example 3 minutes later, the district audio system will automatically re-ring, and once the district audio system is stopped, the district audio alarm will not be re-ringed unless the switch is released. Such a problem can be reliably prevented.

Further, even if the continuous sound stop mode is entered, the stop mode can be canceled by artificially operating the district sound stop switch 17 and the district sound device can be re-activated. The re-ringing operation can be easily performed. The flowchart of FIG. 4 is a control process of the second embodiment of the district sound control unit 14 of the MPU 7 provided in the fire monitoring control board 1 of FIG. 1, and the district sound device is forcibly stopped depending on the operation time of the district sound stop switch 17. It is characterized in that two motes, a mode and a continuous ringing stop mode, are set.

In the second embodiment for setting the forced stop mode and the continuous ringing stop mode in FIG. 4, when the district sound stop switch 17 is continuously turned on for a predetermined time, for example, 3 seconds. Is characterized in that the forced stop mode can be set. Here, the forced stop mode means that if the district audio system is stopped once, no matter what happens, such as when an additional fire detection signal is received from another detector line or fire detector, Is a mode for maintaining the stop state.

The forced stop mode is set by operating the district sound stop switch 17 for 3 seconds or longer. In the normal monitoring state where no fire is received, and when the fire is judged, the district sound device sounds and the sound is stopped. It can be done at any time, such as when doing it. Furthermore, the forced stop mode once set is released by determining that the district sound stop switch 17 is turned on for a shorter time than that at the time of setting, for example, 1 second or more.

As a result, 1 of the district sound stop switch 17
For a switch operation of less than a second, that is, a normal switch operation, the sequential ringing stop mode shown in the first embodiment of FIG. 3 is set and released. Next, as an example of the case where a fire is detected by any of the fire detectors 3 provided in the detector line 2-1 of FIG. 1, the forced stop mode accompanying the operation of the district sound stop switch 17 of FIG. Setting and cancellation of the continuous ringing stop mode will be described.

First, for the ringing of the district bell 6 as the district sound device by the district sound control unit 14 at the time of a fire judgment due to the fire reception of the fire detection signal from the fire detector 3 provided in the detector line 2-1. On the other hand, it is assumed that the district sound stop switch 17 is turned on to confirm the site. The ON operation of the district sound stop switch 17 is the process of step S1 in FIG. 4, and first, in step S2, it is checked whether the forced stop mode is in effect.

In the first operation state of the district sound stop switch 17 after the sounding of the district sounding device, neither the forced stop mode nor the successive sounding stop mode is set. Therefore, the process proceeds to step S3 and the MPU 7 is provided. The other timer 15 'is set as a switch monitoring timer and set to 3 seconds for determining the setting of the forced stop mode, and the timer is started.

Next, in step S4, the time until the district sound stop switch 17 that has been turned on is turned off is monitored, that is, the switch operation time from when the district sound stop switch 17 is turned on to when it is turned off is monitored. Check if it is turned off in 3 seconds or more. If the operation time of the district sound stop switch 17 is 3 seconds or more, the process proceeds to step S5, the forced stop mode is set, and then the switch monitoring timer 15 'is cleared in step S6 to perform the mode setting process. finish.

Therefore, in the setting state of the forced stop mode, the ringing stop of the district audio system is maintained even if a fire is received from another sensor line. On the other hand, step S4
If the operation time from ON to OFF of the district sound stop switch 17 is less than 3 seconds, the process proceeds to step S7 and it is checked whether or not there is a fire. Sensor line 2 at this time
Since there is a fire due to the reception of a fire from -1, the process proceeds to step S8, and it is checked whether the ringing stop mode is being set.

At this time, since the sequential ringing stop mode is not set, the process proceeds to step S9, the sequential ringing stop mode is set and the ringing of the district audio system is stopped, and the switch monitoring timer 15 'is set in step S6. After clearing, the mode setting process ends. The district sound control unit 14 after the continuous ringing stop mode is set in this step S9
Processing is the same as that shown in steps S7 to S14 of FIG.

Next, the processing for canceling the ringing stop of the district audio system when the forced stop mode is set in step S5 will be described. In order to cancel the stop in the setting state of the forced stop mode, the district sound stop switch 17 may be operated for 1 second or longer. When the operation of the district sound stop switch 17 for canceling the ringing stop in the forced stop mode setting state is performed, the process proceeds from step S1 to step S2, and since the forced stop mode is currently set, the step Proceed to S11, and switch monitoring timer 15 '
Set to 1 second and start.

Then, in step S12, the operation time from when the district sound stop switch 17 is turned on to when it is turned off is 1
Check if it is more than a second. If it is 1 second or more, the process proceeds to step S14, the forced stop mode is released, and the switch monitoring timer 15 'is cleared in step S6.
The process for canceling the mode ends. In the state where the forced stop mode is released, if the fire reception is performed, the district sound device is activated.

If the operation time of the district sound stop switch 17 is less than 1 second in step S12, the forced stop mode is not released in step S14 and the set state of the forced stop mode is maintained. Further, assuming that the operation of the district sound stop switch 17 for less than 3 seconds is performed to cancel the district sound ringing stop in the state of the continuous ringing stop mode set in step S9, steps S4 to S7.
Then, it is determined that a fire is occurring, and it is determined in step S8 that the continuous ringing stop mode is in progress, that is, the district sound is stopped by the continuous ringing stop mode. Start ringing and re-ring the device.

On the other hand, when it is desired to set the forced stop mode in the steady monitoring state in which the fire monitoring control board 1 is not receiving a fire, the district sound stop switch 17 may be operated for 3 seconds or more. Further, if the district sound stop switch 17 is operated for 1 second or longer after the forced stop mode is set, the forced stop mode can be released and the sound can be returned to the state of ringing upon reception of a fire. In addition, when the district sound stop switch 17 is operated for less than 3 seconds in the steady monitoring state in which the fire monitoring control panel 1 is not receiving a fire, the determination is made in step S7, and step S7 is performed.
In step 6, the switch monitoring timer 15 'is only cleared, and the process ends.

Further, regarding the setting and cancellation of the forced stop mode and the continuous ringing stop mode according to the operation of the district sound stop switch 17 of FIG. 4, the district sound provided on the display portion 10 of the fire monitoring control panel 1 of FIG. Display control of the stop light 21 is performed. That is, in the setting state of the forced stop mode, the district sound stop lamp 21 is turned on. On the other hand, the district sound stop lamp 21 is made to blink in the setting state of the sound stop mode sequentially. For this reason, it is possible to easily understand whether the forced stop mode or the continuous ringing stop mode is set depending on whether the display state of the district sound stop light 21 is on or blinking.

In the above embodiment, the control processing of the first embodiment shown in FIG. 3 and the control processing of the second embodiment shown in FIG. Area sound control may be performed. In the above embodiment, the district bell was used as the district sound device, but by using a speaker and providing a voice synthesizer, an amplifier, etc. in the district sound drive unit, the fire is announced by voice. May be.

[0044]

As described above, according to the present invention, when the district sound stop switch is operated while the district sound device is ringing, the ringing stop mode is set simultaneously with the stop of the sound of the district sound device. In the continuous stop ringing mode, the district audio device can automatically ring again in response to the reception of an additional fire detection signal from another detector line or another fire detector. Even if you stop the ringing and go to the site confirmation, if a fire signal is received from another sensor line, the district audio system will be re-ringed, and you can be surely notified of a new fire or the spread of the fire.

Further, even in the continuous ringing stop mode, if the district sound stop switch is operated again, it can be ringed again by artificially releasing the stop, and the ringing operation of the district sound device after the site confirmation can be easily performed. In addition, when the certain time required for site confirmation, such as 3 minutes, has elapsed in the continuous ringing stop mode, it will automatically ring again, and the district audio system has stopped even if it took time to confirm the site or could not return due to an unexpected situation. It is possible to avoid the situation of being left alone.

Furthermore, by continuing the operation time of the district sound stop switch for a predetermined time or more with respect to the normal switch operation, even if a fire reception is performed while the sound of the district sound device is stopped, It is also possible to set the forced stop mode without re-ringing, and the sequential ringing stop mode and the forced stop mode can be selected by the operation method of the district sound stop switch, so that the district sound device can be controlled more appropriately.

Furthermore, by providing the district acoustic stop lamps for displaying the setting states of the continuous ringing stop mode and the forced stop mode, it is possible to easily confirm the setting states of different district sound stop modes.
